It includes the sources of energy consumption for <br />all 3 study years using a variety of measurement units and the percent change from the prior <br />study year. Table 2 lists the associated GHG emissions and includes data that is triple normalized <br />for weather, for utility emission rates, and for changed accounts. <br />The chart on the left in Figure 1 demonstrates the large role that electricity plays as regards the <br />City operations' GHG footprint. Fully, 64% of the emissions in 2015 are attributable to its <br />consumption with the remaining portions being natural gas (23%) and liquid fuels (13%). <br />Buildings and facilities (34% of total) and potable water (21 a/6) are the largest sources for <br />electricity -related emissions. The second pie chart in Figure 2 breaks out the combined sources <br />of GHG emissions into the various sectors in 2015. Buildings and facilities account for more <br />than half (53%), potable water is the next largest (24%), followed by liquid fuels (130/o), <br />streetlights and signals (60/6), and finally sewers at 1%. <br />ORANGE <br />ENVIRONMENTAL <br />
